Quadratec and Pro Comp have teamed up to deliver two popular wheel and tires packages straight to your door. Tires are carefully professionally mounted to their wheels using advanced mounting equipment that prevents scuffed wheels during the installation process. We then use a state of the art "road force" balancing machine with the most accurate balancing attainable for even those hard to balance oversized tires. In short, road force balancing "forces" a roller onto the tire tread to simulate the weight that will actually be on the tire as it spins. Tires are spun at highway speeds to ensure that a true balance is attained, which is crucial in performance, particularly for heavier off-road tires. Center caps included.
